Native use of the Ubuntu GUI without VNC
I know this is already on your radar, but thought I'd add the request to see how it ranks. Personally I'd be fine with just native LXDE support, but I'm sure there are those out there that would want Unity( yuck imho ) or Gnome 3 support.
This is a planned feature which we are working on while working to fix other problems as well
Colliebudz did it in 2012
Here's someone running Ubuntu on a Kindle Fire using native display drivers instead of VNC: http://forum.xda-developers.com/showthread.php?t=1677085
If enabling native GUI display, please do not forget external mouse and international keyboard support. For this reason I started using Jump (free) as a VNC client: it has optimal support for external mouse including right click. (I had to reduce screen size by a few pixels though to avoid screen moving around)

Why don't you use Xserver already available for Android: https://play.google.com/store/apps/details?id=au.com.darkside.XServer&hl=es
in combination with xephyr: http://www.freedesktop.org/wiki/Software/Xephyr
I used to have an Nokia N900 (800Mhz, 512MB RAM) and LXDE ran nicely there, faster than on my new SGS3... using the mentioned combination.
